Problem Bake Normal Maps from hight poly mesh to low poly mesh
in 3D View: you may have made a mistake in the scale, always keep in mind to apply scale CTRL + A select SCALE and ROTATION
play a little configuring the maximum distance and the minimum distance, until you get an optimal result or that you like
in edit mode, remember to apply the normal orientation of the faces towards the exterior, to check this you can turn on the normal indicator in  mesh display , select all and press CTRL + N
with respect to the Subdivision surface modifier, you can also play with the levels to see a result that you like, my example is done with this configuration
